BOTTLE-CLOSURE.

' Specification of Letters Patent.

Patented March 24, 1908.

To all whom it may concern:

Be it known that I, WILLIAM H. REID, a citizen of the United States,residing in Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Bottle-Closures, ofwhich the following is a specification.

This invention relates especially to the closures for bottles used fordelivering milk and cream.

The object of the invention is to provide a closure that can be cheaplmanufactured by machinery out of materia like cardboard or pulp-board;which closure can be easily and efficiently ap lied to a bottle, eseciall when the botiile is entirely filled; an whic will be securelyretained in position'and prevent spilling of the contents, and yet canbe readily removed by simply pulling on the to member. 7

n the accompanying drawing representing embodiments of my invention,Figure 1 shows one form of cap conventionally in section, F 2 is a viewof theca with the several disks slightly separate Fig. 3 represents a toview and Fig. 4 a bottom view, Fig. 5 s ows in section and Fig. 6 inside elevation the same cap on a larger scale. 7 shows enlar ed theposition of the when flexed. ig. 8 shows conventionally in section thecap applied to a bottle. F' 9 shows conventiona 1% a cap formed of afeas number of disks. 10 is a view of another form of cap wit themembers slightly separated. Fig. 11 shows the intermediate members ofthis cap. shows ig. 13 is a bottom plan view of the modification; and 14shows conventionally a section on the line a:x ofv Fig. 13'.

The cap'comprises a top member or disk T of a size lar er than the oning n in the mouth of the ottle D, so that the disk will rest on to ofthe bottle; and a series of smaller dis M. The bottle is shown asprovided with an abutment b, and the distance from this abutment to theplane of the top of the bottle, that is, the plane of the bottom of thedisk T, is, in the standard form of milk bottle about of an inch. Theseries of disks M are relatively very thin compared with theirdiameters, and are secured to the top disk T,and are ofa diameter tosnugly fit. in the neck of the bottle being prefera ly of approximatelythe same'diameter. The

aggregate thickness of these su rposed disks is made equal to, orslightly ess than the said depth of the neck to the abutment, five ofsuch disks are shown in Figs. 1 to 8. These disks are formed of aflexible fibrous material, such as cardboard or ulp-board. The to memberis also prefera ly formed of simi ar material, that is preferably of amore tough and tenacious stuff; the other disks being of a poorer grade.These several members are not secured together throughout their entireadjoining area, but at their central portions only, whereby theirmarginal portions are left free to slide upon each other upon flexure ofthe disk, such as caused by pressure or draft at the central portion,

that will tend to dish the disks or bend tlTem' to a concave form.

Any suitable means can be employed to connect the disks whereby theirmarginal portions can slide upon each other, both in the insertion andremoval of the cap; and whereby the marginal portions of the series ofdisks can separate during the removal that will facilitate the punchingof the disks and their assemblage concentricall for the insertion of thefastening means. can be conveniently secured together b means of one ormore wire staples S, as sue a fastening can be formed and applied by theordina wire stitching, and hence form a part 0 the organized machinethat constructs the cap. When such flexure is produced, the marginalportions of the disks will slide upon each other, and produce an effectsimilar tothat illustrated inFi 7; such as is produced when a ack of carare flexed the edge of each car projecting a very small distance beyondthe adjacent cards and givin a somewhat serrated efiect.

' en the cap is inserted in the bottle, the

pressure thereon will cause it to react from the ti ht engagement withthe bottle neck, and t e series of disk memberswill somewhat dish,tending to reduce their diameter and admit them into the neck. In the-0geration of removi the cap by grasping t to disk at its IOJQCtlDg ma in,t e disks will flex and Wil be pulled out y the central connection, sothat the disks will tend to separate at their margins. The pullinglbeingat the central portion, that portion will'be raised while the marginalportionbeingheld by friction of the bottle neck, and-the disks will dishand reduce their diameter, and will he disks be brought out one at atime with the edges separated; similar to the effect of flexing a packof cards and passing the thumb over the edge to engage the cards at oneend and release them successively. It is also found desirable to formthe bottom disk B of a fibrous material that is tough and resilient,compared with the intermediate disksc, d, e and f, that are made of alower grade and consequently cheaper material. This bottom'disk being oftougher material and conse uently offering more resistance to flexure,will serve to hold the cap more securely in position in the bottlemouth, against blows on the edge of the cap that would tend todislodgeit, or to raise it a short distance. This bottom disk also actsin the nature of a protector for the other disks made of a Weakermaterial, and hence liable to unduly compress or bend upon insertion.

In Figs. 10 to 14 is shown a modified form of cap, in which theintermediate members between the top and bottom member or members arenot circular, but poly onal and of the same size as the bottom disk. Thea exes of the olygon lie in the peripher of t e series of isks below thetop mem er, and the diameter of the polygon between 0 positeangles isequal to the diameter of tl e lower disks. The intermediate disks H areshown in Fig. 11 as hexagonal but may have a greater or less number ofsides and angles with the apexes of the angle lying in the periphery ofthe series of dis s.. One or more, preferably two lower disks K arecircular, corresponding to the lower disk B of the other form of cap, ofa size to engage the bottle neck. The apexes h of the disk H coincidewith the circumference of the disk K, that is, are in vertical alinementtherewith, or in the cylindrical surface of the disks K. There arepreferably two of the gollygon disks H interposed between the top iscated in Figs. 10 and 14. The operation of this form of closure wheninserted .in the bottle is substantially similar to that of the closuresabove described herein; that is, the marginal portions of the four diskswill slide on each other, both in the insertion and in the removal ofthe closure into and from the bottle. But between each apex of theintermediate disks, there will be a certain marginal s ace wherein thelower disks project eyon the intermediate disks forming a slight space.This will permit of a slight fiexure of the lower disks upward uponinsertion and will facilitate the insertion of the closure where thebottle neck is of such a size as to cause a very tight fit of theclosure. But the apexes of the intermediate disks extending to theperiphery of the closure will cause the en agement of the neck b theintermediate disks as well as by the l dwer disks, and will result ineach of the disks F and the two bottom disks K, as ind1- having anengagement with the wall of the bottle neck to assist in retaining theclosure in the neck and resist its easy removal. These apexes will alsorevent the bottom disks frombeing unduy bent upward or dished.

Having thus described my invention, I claim:

1. A bottle closure comprising a diskadapted to engage the top of thebottle, and a series of flexible disks of fibrous material secured tothe top disk and fitting into the vb'ottle neck, said series of disksbeing very thin relative to their diameters and secured at their centralportions with the marginal portions free to slide upon each other andalso to separate u on flexure.
